It’s not often you spot a softly glowing sign warning of gravity-changing crystals in puzzle-platformers, but Vitrum fills that niche nicely. On the e-shelf today from developer 9head Games, the indie puzzle-platformer shuffles up the house that Portal built with an array of power-granting crystals, a suitably bloom-ified tech motif, and a throbbing ambient electronica soundtrack worthy of space hibernation.

Solving Vitrum’s Rubik-like room layouts involves harnessing energy from various crystals found during your travels. Most of the granted abilities — a short air dash, a push of energy, and so on — allude to solutions entailing timing and carefully aimed jumps. The real draw is the ability to combine the powers surging in each of your android hands and the almighty gravity crystal that exchanges floor with ceiling on the fly. There’s a cliff-sharp ramping of puzzle difficulty — it’s no easy task to gyrate into a tiny cubby hole surrounded by deadly red crystals after simultaneously air dashing and watching the room spin sickeningly. Good luck.

Vitrum is a 3D, first person, puzzle/platform game.

The main character is an android designed to convert energy from crystals into powers. The android can absorb energy in each of his hands, allowing him to combine different powers. One of the coolest powers is the ability to invert the gravity, because it’s 3d and because the player can freely choose when and where to use it!

Vitrum takes place in a desert laboratory full of different colored crystals. Some crystals grant powers, others are harmful to the android.

The player will have to figure out how to use the crystals, solve the puzzles and finish each stage in Vitrum.

Each crystal color represents a power, explore each color and discover every power the android can execute.
